Cook 16 ounces bow tie pasta according to package directions, only stop cooking a couple minutes before recommended time so that pasta is a bit al dente. Toss the drained pasta in 1 tablespoon olive oil to prevent sticking, set aside.
In a very large bowl, combine 1 cup diced bell peppers, 1 cup diced carrots, 1/3 cup diced celery, 1/3 cup diced green onions. 2 cups halved cherry tomatoes, 8 ounces diced mozzarella, and 1/4 cup grated parmesan. Toss to combine. Add the cooked pasta and toss everything together to combine. Add 8 ounces Italian salad dressing and toss once more to fully combine.
Before serving, garnish with a handful of freshly minced basil and salt & pepper to taste.
